PATENT OFFICE EARL A. IBESSOM, 0F MARBLEHEAD, MASSACHUSETTS, ASSIGNOR TO UNITED SHOE MACHINERY CORPORATION, OF PATERSON, .NEW JERSEY, A CORPORATION OF- NEW JERSEY f HEEL-SEAT FORMING MACHINE FOR OFF-THE-IJAST WORK Application filed April 27,

This invention relates to machines for use in the manufacture of shoes and is herein et al., and in United States Letters Patent No. 1,706,278, granted March 19, 1929, upon application of Rene E. Duplessis, it-has been the practice to mold the heel-seat portions of shoes, thereby to shape them for receiving the'conca-ved attaching faces of'wood hee%s,

n machines of the. type above, mentioned the last is supported upon a block carried by-a jack which is movable into and out of position under the die to position the shoe in operative relation to the die and to place it in a position to facilitate the removal of a shoe from the jack and the placing of anforming operation, the block being provided with a last pin to enter the thimble of the last.

In the manufacture of some types of shoes, for example McKay shoes, after a shoe has been lasted and an'outsole laid thereon the last is removed in order to permit attachment of the sole by through-and-through stitching through the upper and insole, and the shoe is then leveled by direct pressure while the shoe is supported by a heavy iron form which accurately fits the inside sole portion of the shoe. At this stage in the manufacture of the shoe, in order to facilitate holding of the shoe during the edge trimming and edge setting operations which are next performed, the shoe is removed from the iron form and a second last has to be placed in the shoe but the second last used in these operations is not usually of a character to enable the heel-seat forming operation to be carried out, since, for the edge trimming and edge setting operations, it is not necessary that the last fit the shoe accurately. Hence this last is removed before the heel-seat forming operation.

In order that the heel-seat forming oper- 1929. Serial No. 358,655.

ation may be performed satisfactorily While the shoe is off the last, it is necessary that.

the rear part of the sole portion of the shoe be rigidly supported inside the shoe to op pose the action of the heel-seat forming die,

and that the shoe be held from lateral and Y longitudinal movement with respect tosuch internal support.

Objects of this invention are to provide a machine of the type disclosed in the abovementioned patents which will be universal so that it may be used in both on-the-last and oif-the-last work, and to provide novel shoe supporting and holding means to enable the heel-seat forming operation to be effectively and expeditiously carried out upon shoes which have had their lasts removed. Accordingly, with these objects in view, the illustrated machine, which is of the type above referred to, is provided with a jack which is constructed and arranged to be used with a plurality of heel plates'of different sizes in 1 terchangeably, one being selected, and mounted upon the jack, which approximately fits the heel-seatportion of the'interior of a given shoe thereby providing for firmly supporting the shoe during the heel-seat forming op'era tion and at the same time holding it from v lateral movement relatively to the jack. In

order to prevent rearward movement of the shoe relatively to'the plate during the heelseat forming operation, the illustrated maerally of the plate out of the way of the shoe positioned upon the plate so that the opera tor may, without interference of the clamp ing member and while the heel-seat portion of the shoe is under pressure, employ a hammer to pound up and shape the shoe around the heel-seat portion thereof. Movement of the clamping member out of the way of the shoe also facilitates the removal of the'shoe after the forming operation and the placing of another shoe upon the jack. In the illusno I trated machine the clamping member is normally urged toward the supporting plate by a spring, and a stop is provided for limiting the movement of the clamping member toward the plate.

On the other hand, when it is desired to use the illustrated machine for operating on.

shoes on the last, it is only necessary to remove ablock carrying theplate'and to substitute therefor a block carrying a last pin.

lVith the above and other objects and features in view, the invention will now be described with reference to the accompanying drawing and pointed out in the claims.

Referring to the drawing:

Fi 1 shows the top ortion of a heel-seat forming machine illustrating a jack having a shoe supporting plateand a die which cooperate with one another to form or mold a heel-seat portion of a shoe positioned upon the plate,' together with a member for coopcrating with the plate to clamp the shoe in position upon the plate during the'heel-seat forming operation;

Fig. 2 is a side view of the top portion of the jack and its shoe supporting plate, the plate having a shoe positioned thereon and the jack being provided with the member which cooperates with the plate to clamp the" Letters Patent which'ma'y beconsulted for a better understanding of such features that are not hereinaf er described. The illus-' trated machine, like those set forth in the Letters Patent referred to, comprises a shoe sup porting jack 1O pivoted to a shaft 12 1) which'is mounted for reciprocation in the frame 14 of the machine toward and away from a die 16 of the desired shape secured to the frame 14 in any convenient manner. The jack comprises a post 18 having-an upper bifurcated portion 20 arranged to receive a tongue portion 22 of a carrier 24, the lower surface 26 (Fig. 2) of the tongue portion 22 being curved and serrated to engage a curved, serrated surface 28 of the post 18 so that the carrier 24 may be canted at a desired angle to the post 18 for properly reacting against the molding pressure of the die 16. The tongue portion 22 of the carrier 24 is also provided with a slot 30 throughwhich e tends a screw 82 8 carried by the post for clamping the carrier 24 in adjustedposition to the post 18, the slot 30 being wider than the screw 32 which passes through it so that the carrier 24 may be slightly raised away from the serrated surface 28 of the post 18 for setting the carrier at different positions upon the post 18.

When it is desired to operate upon shoes off the last, a block 84 is substituted for the corresponding block disclosed in the abovementioned Letters Patent. The block 34 is supported upon the carrier 24 and is provided with '2. dove-tail flange 36 arranged to lide in a correspondingly shaped recess 38 in the top surface of the carrier 24 to permit an amount of rectilinear sliding movement of the block 34 relatively to the carrier 24 transversely of the shoe to be supported. 8

This sliding movement is limited by a stud 40 (Fi g. 3) slidable in a recess 42 in the carrier 24, the stud being arranged to enter an elongated recess 43 in the bottom surface of is provided with a fiat upper surface 48 3) constructedand arranged to receive a series of supporting plates 50 of different sizes and shapes which serveas 'supports'for the heehseat portions of shoes mounted upon the jack, each of the plates 50 being similar in shape to the heel-seat portion of the last upon which a shoe is made. Each of the plates 50 is rigidly held in correct position upon the block 34 by a stud 52 of considerable length which fits into a recess 54 in the upper I surface-48of'the block 34 and by a short pin 56 dependin fromeach of the plates and arranged to nt into a recess 58 in the upper surface 48 of the block 84 to assist in positioning the plate upon the block and prevent rotation of the plate about its stud 52.

Each of the plates 50 is locked upon the block 34 by a catch 60 which engages a notch 62 in the stud 52. When it is desired to re-' move the plate 50 from the block 34, the'catch 60 is released by manually pushing a rod 64 connected to the catch and extending beyond a side of the block against pressure of a spring 65'carried by the rod 64.

In order to cooperate with the plate 50 for clamping the shoe in positlon thereon as shown in Fig. 2 so that the operator will not' be required to hold the shoe against displacement relatively to the plate as the jack 10 is moved toward the die 16, there is provided a finger 66 mounted for movement toward and away from the plate 50.

The mechanism for supporting the finger 66 and for controlling the operation thereof arm 7 0 having a. downwardly extending portion 72 provided with a cylindrical recess 74 arranged to receive a stud, 76 i (Fig. 2) secured to a, finger supporting member 7 8 about which stud the finger 66may be rocked for purposes later to be described.

In order that the finger 66 may be supported for movement toward and away from the plate 50 for engaging the rear portion of a shoe mounted upon the plate, the finger-supporting member 7 8 is provided with a pin 80 extending therethrough,-upon the end portions of which pin projecting legs 82v of the finger 66 are mounted -tostraddle opposite sides of the finger-supporting member 78.

The lower portions of the finger 66 and the finger-supporting member 78 are. provided with hand grips 84, 86 respectively, supporting between them a spring 88 which tends to rotate the finger 66in a counterclockwise di rection (Fig. 2) about the pin 80 thus normally urging the shoe-engaging portion 90 of the finger 66 downwardly and to the left against the rear portion of the shoe near its sole-when the finger-supporting portion 7 8 is in itsvertical position as shown in Fig. 2.

When it is desirable to move the finger 66 away. from the shoe during the period in which the shoe is under pressure in order that the operator may hammer the rear portion ofthe shoe to shape properly the portions of the shoe surrounding the heel-seat portion of the, sole, or where the block 34 has been removed and a block such'as shown in the above referred to Letters Patent is to-be substituted therefor to ec uip the machine. to operate upon shoes on t e last, the finger 66 together with the finger-supportingmember 78 swung or rocked. about the stud '56 to a position shown in Fig. 3.

In order correctly to locate and set the finger 66 in upright position (Figs. 1 andQ) forclamping the shoeand to permit it to be swung convenientlylaterally of thejacl; as above. described, the: upper end of thede pending portion 72 of the arm '50 is provided with a pair ofslideways 92 (Fig. 3) and a socket94 which cooperates with a spring pressed ball plunger 96 (Fig. 2) mounted in a cylindrical'recess 98 of thetinger-supporu ing. member 78, the plunger 96 being released by positivelyswinging the finger-support-.

ing member 78 together with the finger 66 laterally of the jack about the stud 76. The lateral displacement of the finger 66 about the stud 7 6 at opposite sides of the jack is limited, by shoulders 100 (Fig 2) located upon opposite sides of the depending portion 72 ot-the arm 70, one of which shoulders engages a protruding lug 102 of the fingersupporting member 78 as the finger is displaced from its upright operative position.

The minimum distance between the finger 66 and theshoe supporting plate 50 may conveniently be regulated hy a screw. lOh-the I inner end. 106 of whichisarrangedto engage theupper portion of aface 108 of thefingersupporting member :7 8, which screw extends hold of the handigrips, the finger .66-coming 7 into contact with the;rear end of the shoe .to force itagainst the adjacent portions of the plate for positioning theshoe uponthe plate 5 0 longitudinally relatively to the die, with-. out risk of'contact of the finger with the die as the shoe is pressed between the jack and thedie;.-

' It will be noted thatsince the arm 70 lis attached to the carrier2t that the hand grips 84, 86 may be used to effect angular adjustment of the carrier 2 L relatively to the post 18. Should it-be found desirable to operate upon a shoe upon a last, it isonly necessary to remove. the block 3i and to substitute a. block carrying a; last pin; such as described the above-mentioned Letters Patent, the

finger 66-being swung laterally to a position such; as indicated in Figgfiso that it will not interfere with :the operation of the machine equipped-for on-.thelast work; 5
